How much CO2 will we need?

Question

If the sun is not present to heat it up?

Lets take the sun, or any other heat source, out of the equation and see how these scientists can produce a model that would promote global warming.

Im talking about a globe model with just CO2 and no heat... what temperature would they get?

Answer 1

If we take the sun out of the equation, there would be no heat. Well the planets would all float off into space as the sun holds them in place, BUT that aside, the greenhouse effect cannot continue to happen if there is no heat coming in from the sun! CO2 insulates the planet and traps heat in, but if there is no heat, then it has nothing to trap!

Answer 2

i am assuming that you are speaking of global warming due to pollution. and not just warming up on a summer day.

co2 does not contribute to global warming in that it does not create holes in our ozone layer. co2 is what our plants and trees need in order to produce oxygen for us to breathe. i think your thinkinf of just plain ol' carbon monoxide. and just to let you know. without the sun, what would it matter, when you say no heat that would indicate a temperature of absolute zero. no life could be sustained on earth. your first breathe at that temp and your lungs would freeze. you can't use your theory to prove or disprove anything

Answer 3

If the Sun wasn't present, the Earth wouldn't have formed in the first place.

If the Sun magically disappeared, the Earth would be approximatley 2.725 Kelvin - the temperature of space.

Of course this question has nothing at all to do with global warming.  You could just as easily ask what the temperature be if there were no greenhouse gases in the atmosphere, and it would be 33 deg C colder than it is.  That doesn't tell you what's causing the warming.

Solar irradiance has not changed over the past 30 years.  CO2 concentrations in the atmosphere have.  It's not that complicated.

Answer 4

Absolute 0.

No scientist would (or could, using actual physics) produce a planetary model without a heat source that warms.

CO2 does not produce any heat, it traps it in our atmosphere.  The sunny side of the moon averages about 110 C.  The dark side (night time) of the moon averages about -100.  That's because there are no green house gases (like CO2) to retain the heat near the surface.

Answer 5

absolute zero, but who cares, the sun is there, and our actions cause a slight increase in the amount of energy, from the existing sun, that remains on earth, and that causes a negligible rise in average temperatures, but that minute change is enough to ruin the whole matrix of life on earth.

Answer 6

CO2 works together with the Sun.

The Sun is the basic source of heat.  But, the Sun didn't cause the INCREASE in temperature we've seen in the last 30 years, because solar radiation has been slowly DECREASING.  Proof:

CO2 has increased the temperature by holding more heat from the Sun in, like a blanket.
